Preface:
我的应用程序基于 Flutter - 但需要本机代码实现才能使 FCM 消息正常工作，请参阅下文了解更多详细信息
GitHub问题 #154 https://github.com/ConnectyCube/connectycube-flutter-samples/issues/154以供参考。
我在 iOS 上获取 FCM 通知时遇到了巨大的困难，特别是在我发布到 Testflight 的应用程序上。我已经被这个问题困扰了一个星期，完全不知道如何继续。
Problem
当使用 Xcode/Android Studio 在我的设备上使用调试/发布版本本地运行时，会在后台、前台等收到通知。exact与 Testflight 相同的应用程序，不会通过 FCM 发出任何通知。
这一点至关重要，因为 FCM 提供 VoIP 通知，而 Testflight 上却收不到这些通知，这非常令人痛苦
问题与解决方案？
我发现了 2 个问题（here https://stackoverflow.com/questions/39550615/firebase-notification-not-working-on-testflight & here https://stackoverflow.com/questions/41140631/firebase-push-notifications-not-working-on-testflight-adhoc-release），两者似乎都表明这是 APNS 证书问题（APNS -> Firebase）。我已经重新创建了我的证书并将其添加到 Firebase 控制台（使用相同的.csr所有证书生成操作的文件）
设置/配置：
-
APNS生成密钥并添加到 Firebase
-
能力：
尝试过：
<key>FirebaseAppDelegateProxyEnabled</key>
<string>NO</string>
with:
<key>FirebaseAppDelegateProxyEnabled</key>
<string>0</string>
与 ：
<key>FirebaseAppDelegateProxyEnabled</key>
<boolean>false</boolean>
<key>UIBackgroundModes</key>
<array>
<string>audio</string>
<string>bluetooth-central</string>
<string>external-accessory</string>
<string>fetch</string>
<string>location</string>
<string>processing</string>
<string>remote-notification</string>
<string>voip</string>
<string>remote-notification</string>
</array>

Testing:
测试是在 2 部实体 iPhone（6s 和 8）上完成的。当使用（调试和发布）模式直接从 Mac（Android Studio 和 XCode）构建时，两者都可以与 Firebase FCM 配合使用。从 TestFlight 下载相同的内容时，两者都不起作用。
如果任何人可以提供有关错误配置、设置错误或丢失/不正确的 Swift 代码，或者仅仅是错误或遗漏的见解，我们将不胜感激。
